#Jpegmini windows rar software
As a widely respected software engineer, often referred to as a “Super Programmer”, it is only natural that his image compression project will be adopted by the open source community, followed by the industry as a whole. In addition to developing the ffmpeg media software, he also developed the QEMU hypervisor for hardware virtualization, The Tiny C optimized compiler, a PC-based DVB-T Digital TV transmitter, and many more projects. But that was the situation for H.264 as well, and it didn’t prevent H.264 from becoming the leading video compression standard.įabrice Bellard, as described in a wonderful profile article by Cameron Laird, is an icon in the open source development community. There is a patent pool for HEVC managed by MPEG-LA, and there may be additional “essential patent” holders. One thing to keep in mind is that if a codec is open-source doesn’t mean it is free from IP constraints.
This is in contrast to “the old days” of standardization, where a standard would define the specification only, and then all vendors would implement the spec on their own, and meet again for interoperability testing (also known as “ Plug Fests”) to ensure that their implementations are in fact compatible with each other.

The availability of the source code implementing the standard from day one ensures the wide distribution of software to support the standard across different platforms, and the compatibility of these software implementations with each other. Changes can be proposed at any time, and if they benefit the whole community, they are integrated into the main branch. As a community-sourced project, there is no need to wait for a standards body to approve or ratify it.
Then it took two more years to approve Part 2 (Compliance Testing), and 4 more years for Part 3 (Extensions).īPG on the other hand is an open source implementation that was created in a few months, based on an existing video compression standard (HEVC). The original JPEG standards group was formed in 1986, but Part 1 of the standard was approved only 6 years later, in 1992. Developing a technical standard in a committee is a lengthy process, that requires dozens of meetings (each one lasting several days), thousands of “contributions” (technical documents proposing various features of the standard), and takes several years to complete. The original JPEG standard, and its successors JPEG-2000 and JPEG-XR were developed by international standardization bodies such as ITU and ISO. Why do we think BPG will succeed where JPEG-2000, JPEG-XR and WebP have failed? Read below… BPG is Open Source Based on these results and on evaluating the technical and market advantages of the new format, we believe that in the long run BPG will be able to replace JPEG as the standard format for image compression, gaining support across the whole value chain from cameras and phones through photo editing software, printing and web publishing. With no apparent marketing campaign or industry backing, BPG has quickly gained comprehensive media coverage, including articles in Forbes, The Register and DPReview.Īfter comparing BPG to other image compression formats using the nice online demo, we’ve downloaded the Windows binaries and played around with them a bit, achieving very nice results in compressing images. BPG was developed by Fabrice Bellard, a very well-known software engineer who also created ffmpeg, a comprehensive and widely used platform for media processing.

There’s a new player in the image compression scene: BPG (Better Portable Graphics), a format based on a single video frame of the new HEVC video codec.
